To all lwhoml z't may co'lwern:-A Be it known that "I, Henman?.` AUSTIN, a subject of the King or Great Britain, residing at Lickey Grange, Bromsgrove, in the county of Worcester, England, have invented certain new and useful Improvements in or Relating to-Detachable Wheels, of which the `following is a specification,

ThisL invention relates to detachable wheels for motor road vehicles, and has for its object ,to provide' improved means by which a detachable wheel is secured in relation to the permanent hub.

A convenient application of the invention is described by reference to the drawings herewith, of which Figure 1 is a longitudinal vertical section of the hub and axle end of the front steering wheel of a motor vehicle.

' Figure 2 is a view of the outer face of one ofl the detachable hubs. In this view, althoughthe holes in the hub for connecting the spokes thereto are shown, the spokes themselves have been omitted 'for' the sake of clearness; and,

Figure 3 is a detail view in section.` Y

The portion b of the .permanent hub B has a shortcyli'ndrical surface b2 upon which a cylindrical portion a3 of the removable hub A 1s adapted to slide. The anges d and d of the permanent hub B carvy a set of studs v h each of which is provided .with a nut j,

the latter being formed with tionat' its inner face.

The remofvable hub A is provided with three holes m (see Figure 2) of a diameter a taper porsuiicientv to allow the` nuts j to pass right through.' It)is also provided with a set of holesn each formed taper as shown at n in Figs. I 'and 2 and of'such a diametelthat the4 taper ortion' of the nuts when-screwedup vupon t e studs may tighteninto the holes n. Each of the holes n connects with one of the v vholes m by opening p, the openings] being of ljust suiicient width to clear the s tuds h.

In putting the wheelvin -place its removable.

hub A is put on over the permanent hub fB, and it is, in the irst instance, held in such relation thereto that the nuts 7' coincide with the holes m allowing the removable hub' to I App1ication led July 9,

be pushed on to the fullest extent. The wheel is then given a slight turn in an anticlockwise directionscausmg the studs in effeet to pass through the'openings p and enter the holes n. Thel nuts are then tight.-

lened up` securely with their) taper portlons within the taper holes n. As `the ta er portions of the nuts are `greater in 'ameter than the width of the openingp the Wheel cannot move back until the nuts are again slackened.

In order to provide4 additional security .against the turning of 'the brake drum E in relation to the wheel it is provided withA studs F2 (sce Figure 4),which fit within the .holes m of larger diamter when the. wheel is in place.

In orderto remove a wheel, it is simply necessary to slack back the nuts two or three turns, move the wheel outward slightlg to clear the holes m of larger diameter om studs F and then turn the wheel round in a clockwise direction until the lar erholes m coincide with the nuts, when 't e wheel'is.

free to -be taken off.

` The. advantage of securing the 'hub as:

above described is that the necessity for removing the nuts and washers or the set pins, 'asis now usually the case, is avoided, thus saving the time taken in screwing the nuts cient diameter to be passed over the usual .fasteners carried bythe permanent hub and by which the removable .hub lssecured in place, the smaller of such holesfsbeing of suchdiameter that an inwardly projecting portion of affastener may enter eachfof saidp holes when said fasteners are tightened up,

and al'r opening cut across between the holes of each pair, whereby when the fasteners are slackened back the Wheel may be given a. slight turn in relation to the permanent hub to cause the fastener heads to pass along the Vopenings into the larger holes and permit the wheel being removed, seid openings being of such smaller Width than the diameter of the smaller hole as to I revent the turning of the Wheel until the slackened back.

In Witness whereof I have hereunto signed m'y name this 26th day of J une 1923.
